Understanding Hazards in the Central and Eastern U.S.

Central US Seismicity Map Research and products for loss reduction in the Central and Eastern U.S. is accomplished through partnerships among USGS and academic, government, and private partners. USGS staff are located in the Memphis, Tennessee, field office at the Center for Earthquake Research and Information (CERI), in Golden, Colorado, and in Menlo Park, California.

The map to the right shows earthquakes (circles) greater than magnitude 3.0 since 1974 plotted on the 2008 USGS National Seismic Hazard Map for the central and eastern United States. Warmer colors on this map indicate areas of higher hazard. Larger earthquakes are represented by larger circles.
